BERNHARD BRAND, OF BRAILA, ROUMANIA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 720,398, dated February10, 1903.

Application filed September 29,1902. Serial No. 125,282. (No model.)

To all whom, t Wl/cty concern:

Be it known that I, BERNHARD BRAND, a subject of the King of Roumania,residing at Braila, Roumania, have invented certain new and usefulImprovements in Car-Couplings, of which the following is aspecification.

The subject of the present invention is a coupling for railway-carswhich cau be operated from the side of the car.

The characteristic of the invention lies inv the fact that the couplinghooks or links, as the case may be, are rigidly connected with toothedsectors which are pivotally secured in the fork-shaped end of a draw-rodmoving in rectilineal guides and pressed in a backward direction bysprings and which can be so actuated by means of a toothed eccentricdisk on a shaft provided with a crank-handle or the like at the side ofthe car that a rotation of the toothed disk in a forward direction maybe eifected, and consequentlya turning of the sector carrying` the hookfor the purpose of eecting'the coupling.

In the accompanying drawings is shown an illustration of the invention.

Figure l shows an elevation of the apparatus, partly in longitudinalsection; andFig. 2 shows a plan View of the apparatusfrom above.

In an opening in the rear side of the lower frame l of the car moves adraw-head in the form of a fork 2, which is continued in a backwarddirection by a draft-rod 3. This rod 3 passes through a transverse bar 4of the frame and is provided at its end with a flange or disk 5, bymeans of which the rod 3 slides in a cylinder 6. Between the end wall ofthis cylinder and the disk 5 is arranged a spiral spring 7, which causesthe rod 3 to be always returned into the position shown in Fig. 1. Thefork 2, which is provided with transverse slots 8 in its branches,carries the toothed sector 9, which in its turn carries twocoupling-hooks 10 or links 1l, as the case may be, at an angle of ninetydegrees to one another. On the stems 10au or 1la of these hooks or linksmovable plates l2 are provided, which by means of springs 13 are pressedagainst the front end of the fork 2, and by this means an automaticturning of the sector 9 with the hooks or links is prevented. Throughthe said slots 8 in the fork 2 passes a shaft 14, upon which is keyed acombined eccentric and toothed disk 15. The arrangement on the oppositecar is precisely identical, with this exception, that if on the firstcar the hook 10 is-vertical on the second car the hook 10 lieshorizontally. On both 'sides of the ear the shaft 14 carries acrank-disk or other handle to rock the shaft.

The apparatus isactuated as follows: To effect a coupling, the two carsare moved toward each other and the hooks and links automaticallyengage. If two cars which are provided with and coupled by means of thisapparatus are to be uncoupled, one may advantageously move the hook orthe link of one car from its previous position by turning the crankarranged at the side of the car, so turning the shaft 14 of this carinthe direction of travel of the hands of a clock, upon which theeccentric formation of the disk 15, working in conjunction with thetoothed sector 9, overcomes the iniuence of the spring 7 and pressesforward the fork 2. Upon this, however, there follows an engagement ofthe toothed sector of the disk 15 with the teeth of the sector 9, as aresult of which the latter is rotated and the link 10 or hook 1l, as thecase may be, is removed from engagement.

The special construction of the apparatus may be altered Withoutdeparting from the nature of the invention.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. -In a railway-car coupling, the combination of the frame l, atransverse bar 4, a draftrod 3 sliding therein, a spring 7 influencingsaid rod, said spring being inclosed in the cylinder 5, with a disk 9carrying the hooks and links of the coupling,and pivoted in the forkeddraw-head 2 attached to the draft-rod 3, all coperating, substantiallyas described.

2. In a railway-car coupling, the combination of a draw-head, a shaft 14provided with toothed eccentric disk 15, a toothed sector 9 carrying thehooks and links forming the coupling, said sector 9 being pivoted inthedraw-head, the latter' being capable of moving against the inuence of aspring 7, all cooperating, substantially as described.

3. In a car-coupling, the combination with a draw-head, of a pivotedcoupling.r device having a toothed sector, a transverse shaft having atoothed eccentric disk for engaging said sector, a plate on the couplingdevice, in front of the toothed sector, and a spring tending to presssaid plate toward the sector, to lo normally prevent movement of thesector on its pivot.

In testimony whereof I have hereunto set my hand in the presence of twoWitnesses. BERNHARD BRAND. Witnesses:
